Study type: Medical/biological study (experimental study)

Magnetic field-induced changes in specific gene transcription med./bio.

Published in: Biochimica et Biophysica Acta - Gene Structure and Expression 1992; 1132 (2): 140-144
Journal partially peer-reviewed/peer-review process unclear

Aim of study (acc. to author)

To investigate the effects of magnetic fields on the c-fos, c-myc, c-jun and protein kinase C transcription rate in human lymphoblastoid cells.

Background/further details

The influence of exposure time and cell culture density (5x105 cells/ml and 106 cells/ml) were further investigated in order to explore their relevance on magnetic field induced changes.
